Pumps Department offer

Pumps type WM and WMs – construction:

Pumps of WM and WMs type are impeller, centrifugal pumps working in “in-line” system with horizontal parting of the body. The pumps are selaed with Burgman mechanical seals. The pumps are adapted for opearting with self-suction pumps of Pa type (made in GZUT S.A.). They are driven by a 50 Hz or 60 Hz electric alternating current motor. The electric drive is transmitted by an inseparable flexible coupling.

The pumps are adapted for operating in manual or automatic control system. The construction of the pump enables its easy disassembling without motor and pipe connections dismounting.
Pump parts being in contact with pumped medium are made (depending on ordered version) from cast iron (EN-GJL-250) or from aluminium bronze (CuAl10Fe5Ni5-C). An impeller and its rings are made solely from aluminium bronze. A shaft is made from stainless steel type H17N2

Pumped medium:

fresh water, sea water,

oil of viscosity up to 36,2cSt.

The maximum temperature of pumped medium:

up to 95°C (368 K) – fresh water and oil

up to 45°C (318 K) – sea water.

Application:

In shipbuilding:

sea and fresh water cooling systems,

bilge systems,

ballast systems,

fire-fighting systems.

In land execution:

stationary fire-fighting systems,

public and industrial water supply,

mining,

power industry.

Advantages:

High efficiency, reliability, simple construction, small amount of components, easy to service.

Parameters:

capacity: Q = 25 ÷ 1000 m3/h

delivery head: H = 20 ÷ 120 m

maximum manometric suction head for clean water in temp. 200C an atmospheric pressure 760mmHg is from 5 to 7m (depending on the pump).

Vertical impeller pumps WL and WLs – construction:

Pumps of type WL and WLs are centrifugal, single-stage vertical impeller pumps driven by a 50 Hz or 60 Hz electric alternating current motor. The electric drive is transmitted by an inseparable flexible coupling. The pump body is divided along a vertical plane. The pump’s flanges are of the same diameter, located at the same height in relation to the pump base.The shaft with rolling bearings is sealed in the stuffing-box by one mechanical seal. The pump construction enables its easy disassembling without motor and pipe connections dismounting.The WL pump is not capable of sucking the liquid itself. WLs pumps are equipped in a vacuum pump Pa and can operate as self-suction pumps.

Considering the material used for the pump’s casing and stuffing-box there are two versions of pumps:

type M – material: grey cast iron;

type T – material: bronze.

Pumped medium:

Pumps WL and WLs are suitable to pump the following mediums: fresh water, sea water and oil of viscosity up to 5°E (36,2cSt).

Other liquids can be also pumped when agreed with manufacturer.

The maximum temperature of pumped medium:

fresh water and oil – up to 95°C (368 K),

sea water – up to 45°C (318 K).

Application:

In shipbuilding:

sea and fresh water cooling systems,

bilge systems,

ballast systems,

fire-fighting systems.

In land execution:

stationary fire-fighting systems,

public and industrial water supply,

power industry.

Nominal parameters and dimensions:

– capacity:

Q = 25 ÷ 1000 m3/h

– delivery head:

H = 15 ÷ 80 m at 50 Hz

H = 25 ÷ 120 m at 60 Hz

– synchronus speed:

n = 1500 ÷ 3000 rpm/min at 50 Hz

n = 1800 ÷ 3600 rpm/min przy 60 Hz

Vacuum pumps Pa type – construction:

Pumps of type Pa are liquid ring, vertical impeller pumps driven by a 50 Hz or 60 Hz electric alternating current motor. The electric drive is transmitted directly (without coupling) from an engine to a pump’s shaft which whose end part is mounted on an engine shaft.The pump’s body is divided on a horizontal plane and it makes up a container with an inner system of suction and press chambers and pump connection’s holes

The suction hole is for the connection of the vacuum pump to the suction side of the pump system.

The press hole is for the draining of air and removing liquid from the pump system.

Two rubber rings seal the pump’s shaft. Pumps are manufactured in two material versions:

execution M – grey cast iron;

execution T- bronze.

Applitation:

The main function of the vacuum pump of type Pa is to create a vacuum both in the suction pipeline and the impeller pump. It causes the pumped liquid to be sucked into the impeller pump and makes normal work possible. Vacuum pumps Pa are designed to work together with horizontal and vertical impeller pumps made by GZUT Inc. They also can be used for operating with other manufacturers’ pumps but it should be agreed with GZUT Inc. The Pa pumps can operate together with impeller pumps of a capacity up to 1200 m3/h.

Dimensions:

Piston pumps TKE type – construction:

Pumps of TKE type are double-piston, double-acting vertical pumps driven by a 50 Hz or 60 Hz electric alternating current motor. The electric drive is transmitted by an inseparable flexible coupling and gear-box. The basic components:

pump body with two water cylinder

gear-box with intersecting axis gear

valve-box with valve-system

overflow device with safety-valve set on pressure which guarantee that ordered parameters are received..

Pumped medium:

fresh water, sea water and oil of viscosity up to 5°E (36,2cSt). Other liquids can be also pumped when agreed with manufacturer. The maximum temperature of the pumped medium is: 45°C (318 K)..

Application:

In shipbuilding:

bilge systems;

ballast systems;

fire-fighting systems.

The can be used on land as a residual pump with low pumped liquid level.
